BIND 9.5 on Fedora Core 9 not resolving dns queries
Hi there,
I have this ISP grade Nameserver running on BIND 9.5 on Fedora Core 9 64 Bit.
Its been pretty working well for sometime until a last week when we noticed it stopped resolving for our clients using on our service.
It gives correct authouritative answers for our own ISP domain with the A, PTR and MX intact but does not return resolving queries back to clients.
Below are my files
My named.conf file
//
// named.conf for Red Hat caching-nameserver
//
options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
recursion yes;
